- Click the alignment. Click
Find. - In the Alignment Properties dialog box, click the Design Criteria tab. Note: To use criteria-based design, an alignment must have at least one design speed.
- In the Design Speeds section, click
Add Design Speed. - Specify the Start Station and Design Speed values.
- Repeat Steps 3 and 4 to specify design speeds at other stations.
An alignment can have unlimited numbers of design speeds, but can have only one speed at any given station. When a station has a design speed setting, that setting applies to either the remainder of the alignment or the next station at which a design speed is set. If a single entity has multiple speeds assigned to it, the highest speed is used to validate that entity against the design criteria. The lower speed values are ignored.
- On the right side of the dialog box, select the Use Criteria-Based Design check box.
